APOD: 2025 October 13 Б Lemmon Tree

Explanation: The tree is not in danger. That's because the comet pictured just above it, Comet C/2025 A6 (Lemmon), is far in the distance, well away from the Earth. Comet Lemmon now continues to brighten as it arcs through the inner Solar System, even though it has passed its nearest to the Sun -- because it is now approaching the Earth. The comet will likely appear brightest when it is at its closest to the Earth next week, then closing to about half the Earth-Sun distance. Comet Lemmon may then be visible to the unaided eye, but it is more likely to be imaged by a camera phone -- if you know where to look. Comet Lemmon, previously best visible in the morning, is now also visible in the evening sky for northern observers: look above the western horizon just after sunset. The featured image, centered on an unsuspecting European beech tree, was taken in Slovenia about ten days ago.
